Patented Sept. 16, 1930 PATENT OFFICE ANTHONY C. MCGINTY, F LOS ANGELES, CALIFORNIA ROTARY MOTOR Application led February 13, 1929. vSerial No. 339,613.

This invention relates to rotary motors, and more especially to that class of rotary motors operating upon the turbine principle.

An object of the invention is the provision of a novel design of turbine, in which the housing and the rotor vanesv are elongated, with the result that a greater area of vane Y 1 may be exposed to the jets. This construction results inthe development of a `given amount of power bymeans of a turbine occupying a smaller space than one constructed according to conventional design. Y

A further object is the provision of a turbine of-the general class'described, which is composed of a very few ypartsand which is of exceptionally simple design, with the result that a turbine embodying the principles of my invention, may be constructed at a reli atively low-cost, and still will operate with 'A further object is the provision of a novel method of journalling therotor shaft and of supplying the journals of the shaft with lubricant. l

A still further object is the ,provision of a turbine of the general character described,

' in which thevanesare fluted on their traili ing sides, theflutings extending lin parallel- Y respect to the vanes.

' ism with the rotor shaft, thepu'rpose being to add to the eiciency ofthedevice by minimizing the vslippage of the motive fluid in A still further `object is the provision of A a turbine having an elongated tubular housing and a rotor shaft journalled co-axially thereof, and rotor vanes constructed in units of such a naturefthat additional units of vanes may be mounted on the shaft within `if vit be desired toldevelop la greater amount 17 the housing, and additional nozzles provided of power with `a given size of housing.

The invention possesses other v obJects `and i Vadvantageous features, some ofwhich, with those enumerated, will beset forthinthe following descriptionv ofthe 'inventions particular embodiment which is illustrated in the drawings accompanying and forming a part of thespecification.

Y Referring .to the drawings:

Fig. 6 is a vertical, transverse sectional view taken upon the line 66 of Fig. 3, with the direction of view as indicated.

Fig. 7 is an end elevation taken in the direction of the arrow 7 of Fig. 3.

Specifically describing the prefered embodiment of the invention, the turbine com- The forward and after ends of the housing 11` are closed by heads 16 and 17 respectively, which are preferably tightly fitted into their associated ends of the tube 13,7and each of which is provided with a flange 18 extending therefrom, adapated to engage the associated end of the housing and limit the distance that the head may be pressed into the housing. Any convenient means may be employed for .rigidly securing the heads in position, such as screws 19 extending through the tube 13 into the' associated head 16 or A partition 21 is also provided within the housing, this partition being fitted within the bore thereof and disposed between the heads 16 and 17, preferably closer to the forward head 16 than to the after head 17. A rotor shaft22 is journalled within, and extends through the after head 17 and the partition 21.` This shaft is disposed co-axially within the housing 11, and carries a rotor Y nnit 2S-Which comprises a plurality of radiallyjextendingvanes 24. Each of thesey -vanes is extended inadirection parallel tothe shaft` 22, sothat it is of'greater Width than length,
